"Forgot to mention that this 70 horse, 6 cylinder, from about 1975 has no brass ID plate mounted anywhere. I bought the boat from the guy who built her, but he was sick and died and never had the chance to ask him a question. I have just babied this engine ever since with oil, filter, belt, zinc, impeller, hose changes etc, for the last 10 years. never had any problems, but is she a keeper even though so old?"
